Dans notre approche, chaque image de la base est repr\'esent\'ee par un descripteur dit multi-niveau, qui stocke les descripteurs des quadrants de l'image, obtenus par une d\'ecomposition de l'image en arbre quaternaire. L'arbre QUIP permet de regrouper les images en clusters, en fonction de la similarit\'e de leurs quadrants. Cette structure d'index permet non seulement des recherches globales d'images par le contenu, en appliquant un filtrage multi-niveau via l'arbre quaternaire, mais aussi des recherches d'images similaires par r\'egion.
Abtract in english: This article presents a quadtree-based data structure for effective indexing of images. An image is represented by a multi-level feature vector, computed by a recursive decomposition of the image into four quadrants and stored as a full fixed-depth balanced quadtree. A node of the quadtree stores a feature vector of the corresponding image quadrant. A more general quadtree-based structure called QUIP-tree (QUadtree-based Index for image retrieval and Pattern search) is used to index the multi-level feature vectors of the images and their quadrants. A QUIP-tree node is an entry to a set of clusters that groups similar quadrants according to some pre-defined distances. The QUIP-tree allows a multi-level filtering in content-based image retrieval as well as partial queries on images.}, pdf = {http://www.lamsade.dauphine.fr/bdgl/PS/GJMMVOMR_BDA2004.pdf}, url = {http://www.lamsade.dauphine.fr/~manouvri/Slides_BDA2004_QUIP.pdf} }
